Since I encountered BeOS 5 Personal Edition, my experience with BeOS PE led me to purchase the BeOS 5 Professional Edition, which I used for some years. I am not ashamed to say that I love using this OS. After the demise of Be Corp., I still used BeOS as my "main OS" since it would do everything that I needed to do, except for gaming and academic works. I closely followed all the developments of the BeOS contenders after Be's fall... Until Zeta OS became the leading standard for a short time. I purchased every Zeta OS release that YellowTab produced. It is currently my favorite BeOS version today.
